Please weigh in on my post. I noticed you provide a lot of good advice and you're knowledgeable. I'm doing my first DIY solar install in a campervan conversion. I'd appreciate your opinions and advice. Thanks

Can you provide a little info about your 2 panels (series or parallel)? What SCC do you have?
The 390w panels will be pretty high amps so connecting a 3rd (identical?) panel will need to be compatible with wiring (all unknown to me) and the SCC input voltage limits.
